BorgWarner Turbine Housing SX S400 A/R 1.10

BorgWarner is a well-known name in the turbocharger world, trusted for their durable and reliable components. This SX S400 turbine housing, with an A/R ratio of 1.10, is designed for serious performance builds where airflow and exhaust gas management are critical. It's a key piece for anyone looking to optimize their S400 turbocharger for higher horsepower applications.

The 1.10 A/R ratio means this housing is built for better flow at higher engine speeds. This helps the turbocharger spool up effectively and maintain boost pressure as RPMs climb, making it a solid choice for drag racing, sled pulling, or any application where sustained power is the goal. The cast iron construction is robust, intended to handle the high temperatures and pressures associated with performance turbocharging. This housing is a direct replacement for the stock S400 turbine housing, simplifying installation for those already familiar with the S400 platform.

When installing a new turbine housing, it's important to ensure all mating surfaces are clean and that proper exhaust manifold gaskets are used to prevent leaks. While this housing is designed for the S400 series, always double-check compatibility with your specific turbocharger model and supporting modifications to ensure optimal performance and longevity. This part is not CARB approved and cannot be shipped to California.
